Abstract: Apparatus for Sensing Non-Coded Images Abstract of the Disclosure Scanning apparatus is provided for sensing non-coded images on a substrate.  Hand-held scanning apparatus comprises a group of light sensitive elements for sensing the light and dark pattern of the image as the scanner is moved across the substrate and means for sensing the velocity of the scanner.     The velocity determination is carried out through sensing means which comprise  an X-Y coordinate grid positioned between the scanner and the substrate, means for sensing the rectilinear component of move-ment of two positions on said scanner with respect to the X lines in said grid together with the means for sensing the rectilinear component with at least one position on said scanner with respect to the Y lines on said grid.  With this capability of calculating the rectilinear components of three such points or positions, the velocity of a given movement of the scanner in the X-Y and .THETA. (rotational) directions may be determined. In this manner, the scanner is able to sense lines of the image relative to the velocity of movement of the hand-held scanner which is all that is necessary to record and reproduce the image.

Abstract: TITLE Water Evaporation Process ABSTRACT An energy-efficient water evaporation process uses a falling film evaporator having a plurality of substantially vertical and equidistant heat exchange elements made of a synthetic polymeric material.  Each evaporating surface is in contact with a liquid spreading means, and each heat exchange element is heated by steam having a condensation temperature slightly higher than the boiling point of the aqueous solution from which water is being evaporated.  Steam formed by evaporation of water either is recompressed and reintroduced as heating steam in a single-stage process or is used as heating steam for another stage, operating at a lower temperature and pressure, in a multistage process. Heating steam condenses to fresh water, which is recovered.  This process is operated at a low feed rate, preferably below 45 Kg of incoming aqueous solution per linear meter of horizontal width of each evaporating surface, and is capable of providing a 50% fresh water recovery per pass from sea water. Higher recoveries are possible in the case of brackish waters and various industrial waters.  The process is useful in water desalination and purification.

Abstract: RECOVERING HEAT FROM BURNING ELEMENTAL PHOSPHORUS           ABSTRACT Large quantities of valuable heat can be recovered from burning elemental phosphorus by bringing together in a reaction zone elemental phos-phorus and a sufficient amount of oxygen in a free-oxygen containing gas to form phosphorus pentoxide in a product stream while maintaining the mole ratio of water to phosphorus pentoxide to less than 1:1 in the product stream.  The product stream from the reaction zone is cooled to a temperature not less than the dew point of any component in the product stream, prefer-ably to a temperature not less than about 100°C. above the dew point of any component in the product stream, by contacting the product with a metal cooling surface containing a heat transfer fluid to maintain the temperature of the metal cooling surface at least about 100°C.

Abstract: ABSTRACT OF THE DISCLOSURE      An improvement in the cyclic process for producing urea wherein CO2 and NH3 are reacted in the presence of an aqueous ammoniacal solution in a urea synthesis reactor at an elevated temperature and at an elevated pressure in excess of 1800 PSIG to form a urea synthesis reactor effluent fluid at high pressure.  The said effluent fluid is split into a minor stream and a major stream.  The major stream is let down in pressure and then passed into a gas liquid separator wherein the gas stream rises through a packed midsection into the upper portion of the separator and is then taken off.  The minor stream is cooled and then let down in pressure and passed into the upper portion of the gas liquid separator to produce a gas phase which is taken off from the upper portion and a liquid phase which passes down through the packed midsection and contacts the upwardly rising gas phase from the major stream wherein the downwardly passing liquid phase absorbs carbon dioxide and water vapor from said upwardly passing gaseous phase.  The said liquid phase enriched in carbon dioxide and water vapor is then taken off from the lower section of the separator and with-drawn together with the liquid phase portion of the major stream.  This liquid product is passed to a carbamate decomposer.  The gaseous product taken from the upper section of the separator is, after further processing, at least in part recycled to the urea synthesis reactor.

Abstract: Abstract An uninsulated tank-type solar collector for a reverse-refrigeration-cycle heating system is mounted in ambient air and contains a mass of water and/or ice having a refrigerant expansion coil immersed therein.  At least one of the walls of the tank contacts ambient air on one surface, and the mass of water and/or ice on the other surface. Thus, the mass of water and/or ice exchanges or transfers heat from the ambient air by conduction to the expansion coil. During transition from water to ice, the freezing water liberates large amounts of energy as "heat of fusion" which is absorbed by the expansion coil.

Abstract: Abstract Of The Disclosure A sintered metal body, having an annular form suitable for use as  a valve  seat or  seal,  is impregnated with an uncured polymeric material such as PTFE which is then cured to partially fill the interparticulate spaces in the sintered metal body.  The impregnated body is then subjected to applied pressure which preserves the annular shape of the body while collapsing substantially all voids throughout the body to cause the cured polymeric material within the sintered metal body to completely fill the collapsed interparticulate spaces thereby to render the body nonporous throughout.          Inasmuch as the interparticulate spaces are completely filled with cured polymeric material, any increases in temperature of the body which result in an expansion of the polymeric material cause a migration of portions of that material from the interior of the body to the exterior surfaces of the body to lubricate the exterior surfaces.          The body may, in addition, be completely covered by another layer of cured polymeric material to give the seat additional initial lubricity.
